WILLIAM OLIVER BAILEY, OF LONDON, ENGLAND.

APPARATUS FOR BEVELING GLASS.

SPECIFICATION forming part of Letters Patent No. 645,883, dated March 20, 1900.

Application filed March 7 1898- Serial No. 672,951. (No model.)

T0 ctZZ whom it may concern:

Be it known that I, WILLIAM OLIVER BAILEY, glass merchant, silverer, andbeveler, a subject of the Queen of Great Britain, residing at the Excelsior Works, IVenlock Road, City Road, London, England, have invented certain new and useful Improvements in or Belating to Machines or Apparatus for Bevelin g Glass, of which the followingis a specification.

My invention relates to that class of machines for beveling glass disclosed in British Letters Patent No. 11,382 of 189 1 and No.

7,334 of 1895; and it consists in the featuresand detailsof construction and combinations of parts which will be hereinafter more fully described and claimed.

- In the drawings forming part of this speci-- fication, Figure 1 is a side elevation, partly in section, of the complete apparatus. Fig. 2 is an end-view of the frame and easel. Fig. 3 is a longitudinal section of -.the easel-adjust. ing gear. Fig. 4 is a section on the line a a of Fig. 3. ing mechanism foroperating the easel-projecting gear. Fig. 6 is a plan view of'a portion of Fig. 5. Fig. Tisha rear elevationof-a part of the frame, illustrating thegripping mechanism. Fig. 8 is a section on the line b b of Fig. '7. Fig. 9 is a detail View. I Fig,

10 is a side view of the means for operating the straight-edge or clamping-board. Fig. 11 is a rear view of a portion of the easel, illus'- tratingthe means for locking the bufiers in 7 position. Fig. 12is an enlarged sectional View of one of the buffers. Fig. 13 is a front ele, Vation of the easel on a reduced scale, Fig. 14 is an elevation of the clamping-board, and Fig. 15 is a plan view of the same.

In Figs. 2, 3, and 4 is shown the improved arrangement for effecting the adjustment of the easel of the frame (which carries the glass to be beveled) to the required angleof bevel and to the required depth of cut. This con sists in combining the projecting mechanism with the angleadjustingmechanism, whereby the frame is rendered more accurate and generally more satisfactory in use. This I effect by forming each of the usual sliding bars f of a double dovetail and trough section, as shown by Fig.4, sliding in suitable guides f on the frame. This barf carries the easel g, hinged thereto at its outer end, Fig. 2, the

Fig. 5 is an elevation'of the feed easel being supported by two or more struts g, jointed to the easel and at f to a sliding block f capable of sliding onthe barf. The sliding, block f is operated by a threaded rod f acting on a lug-nntf attached to the block f ,the rod being supported by the barf and prevented from movinglongitudinally therein by the grooved end and bolt f The other end of the rod f is carried by the frame and is provided with a worm-pinion h, in which the rod is free to slide, but prevented from rotating therein by a feather or other suitable means. The worm-pinions h of all the sets of adjusting mechanism are operated by a handwheel and shaft 2', provided with worms 2'.

. ried by the frame, as shown in Fig. 3, in which figurethe angle-adjusting block f is shown drawn back and the barf is shown projected forward. Suitable scale-marks may be cut uponthe sliding bars to facilitate the adj ust-' m'entthereof.

In order that the barf, carrying the ease], maybe projected without attention and thus automatically regulate the feed, I provide the mechanism shown by Figs. 5 and 6', in which It represents the worm-shaft which carries thev'oims In, Fig. 3. This shaft is is fitted with a toothed pinion gearing with an intermediate toothed wheel k formed with a toothed pinion k The latter gears with a toothed wheel k attached to a ratchet-Wheel is, arranged as shown. The ratchet-wheel is operated by a pawl Z, mounted at one end of a bar Z, capable of sliding in a bracket Z the other end of the bar being provided with a roller Z and spring Z. This pawl-bar Z is moved longitudinally by cams fixed to the lower rail on which the frame runs. The cams are arranged as shown in Fig. 6, m being a cam pivoted toa bracket at m and held against the wall or stop m by the spring m It will be seen that the cam only acts upon the pawl-bar Z in one direction, the bar Z causing the cam on to yield against the power of the spring m when traveling. backward.

For propelling the frame across the face or bevel of the mill I employ a continuously-moving endless rope or chain at, stretched between adjustable grooved pulleys suitably mounted on the walls of the building, and utilize the opposite moving directions of the upper and lower rope to give corresponding motions to the frame. For this purpose I provide two pairs of jaws n 91 mounted in suitable guides or, Figs. 7, 8, and 9, and operate the same by means of a shaft a, each end of which is cut with a right-hand and a lefthand thread fitting the internal threads of each pair of jaws. (Respectively and clearly shown in Fig. 8.) The shaft is fitted with a bevel-pinion o, in gear with a bevel-wheel 0, which is integral with the toothed pinion 0 the latter meshing with the sliding rack 0 carrying the arm 0 The rack 0 is also provided with a starting or stopping rod 0 which passes across the back of the frameto a convenient position for use. The arm 0" is operated automatically by suitable projecting stops fixed to the lower rail, so that on the frame arriving at a stop the motion of the arm 0* is arrested, whereby the motion of the frame causes the rack 0 to act on the bevel-gearing o 0. This causes one or other of the pairs of jaws to grip either the upper or lower rope or chain, whereby the necessary reciprocating motion of the frame is obtained.

The glass plates are held on the easel by a clamping-board or straight-edge 19, carried by a pair of quadrants 19', Fig. 10, pivoted at gfiat each end of the easel g. The quadrants are toothed, as shown, and gear with toothed wheels p mounted on one shaft. One ofthe wheels 5 gears witha pinion p suitably mounted on the ease], the pinion 13 being operated by a crank-handle, or the crankhandle may operate the wheel g direct. The toothed wheel 10 is integral with a'ratchetwheel p and a pawl 19 is provided to prevent the backward rotation of the toothed wheel p and consequent falling away of the'clamping-board.

The easel g, over the front of which a thin sheet of rubber is hung, is provided with a number of rubber buffers r, mounted on stems r, passing through the easel and pressed outward by springs W, as shown in Figs. 12 and 13, the latter figure illustrating the positions of the buffers on the easel with the rubber covering removed and the former showing the construction of the butters. T represents a fly-nut for adjusting the projection of the buffer from its case. The lowest row of buffers are capable of being locked to prevent the springs yielding after the glass has been clamped in position. This I effect by providing at the back of the easel a lock for each of the buffers. (Shown in Fig. 11.) It consists of a lever .5, pivoted to the case at s and arranged to grip the stem 0* of the buffer 1* between it and the correspondingly-curved surface .9 of the lock-case. All the levers (of which there are as many as there are bufiers in the lowest row) are forked at their lower ends and straddle the rod 15, swivel-jointed at t to a threaded shaft 1 carried by the bracket i, which is correspondingly screw-threaded, the shaft carrying a hand-wheel (not shown) for rotating same. The rodt is also screwthreaded and fitted with nuts 25, between which and the forked end of the levers s the springs 8 are fitted, the nuts 25 permitting the adjustment of the pressure of the springs against the lever 8, thereby insuring sufficient and simultaneous pressure on all the levers s. i are collars arranged to release the gripping action by pulling ofif the leverss when the shaft t is rotated in an opposite direction to that which causes the gripping action.

The clamping-board p is formed with its inner face rubber-covered and perfectly level, so that when the glass is clamped between it and the easel the outer surfaces of the glass plates are all truly level, the spring-buffers 1' pressin gall the glass plates against the clamping-board and, in which position the lowestrow of bufiers is fixed by the locking mechanism previously described. By these means the various thicknesses of glass are accommodated and rendered capable of being operated upon simultaneously. Thelower edge of the easel g is provided with a rail or ledge a, hinged thereto, which is used to temporarily support the glass on the easel when the clamping-board is'removed. v V

In order to insure the clamping-board being as nearly as possible level, I form the outer side'as shown in Figs. 14 and 15. Y readily understood, 'v are straining-bolts carrying caps or plates 'v, to which are jointed the adjustable'links r Any n'umber of sets of straining-bolts and links may be used'to gain thedesired end, and webs or ribs, such as w, may also be employed to add additional stiffness. The block or roller 3 Fig. 10, m arranged between the easel and the quadrant p','so that when the cl amping-boardpis being forced against the glass to clamp the same the quadrants are prevented from str'aini'ng'inward toward each other, and thus prevent bowing of the clamping-board.
